The company adheres to the "variety, quality and efficiency" road. We have established a technology center, a brand cultivation management system and a quality control system. Now the company has formed an independent innovation system integrating S900MC construction machinery steel production, learning, research and marketing. Our company has passed ISO9001 quality management system certification and ISO10012 measurement management system certification.

Hot continuous rolling can be divided into ordinary carbon structural steel, low alloy steel and alloy steel according to materials and properties. According to the different uses, it can be divided into: cold forming steel, structural steel, automobile structural steel, corrosion-resistant structural steel, mechanical structural steel, S900MC construction machinery steel, welding gas cylinder and pressure vessel steel, pipeline steel, etc. We adhere to the tenet of "customer first, quality assurance and good reputation", and always provides high-quality products for our customers.

304 stainless steel plate products have strong corrosion resistance. For ordinary alkali solution and organic acid, inorganic acid has good corrosion resistance. This material S900MC construction machinery steel is a high alloy steel, which can resist corrosion in air or chemical corrosive medium.

S900MC construction machinery steel, Weathering steel plate is a kind of common steel plate. For ordinary steel plate, if it is used for a long time, it will contaminate the steel surface with a layer of rust, which will seriously affect the normal use of steel. Although the weathering steel plate will produce rust, this layer of corrosion is like a layer of dense oxide film, which is firmly attached to the steel surface to prevent the further corrosion of the base and steel. There are many weathering steel plate manufacturers will adopt some corrosion treatment methods.
